XmoFlake

Development

# Will generate .cabal file from package.yaml using hpack
# (that's only really needed to give hints to haskell-language-server)
# It will also provide you all dependencies and haskell-language-server
nix develop

# To build run
nix build

Integration suggestion for use with nixos/home-manager

Add input:

inputs.xmoflake.url = path:Xmoflake; # recommend cloning repo, and using path, so you can more easily change stuff

(If xmoflake is a local git repo, you need to use flag submodules=1 like so sudo nixos-rebuild switch --flake '.?submodules=1#')
Add in your nixos-config like so:

{ nixpkgs.overlays = [ xmoflake.overlay ]; }

Can for instance be used like this in home-manager:

xsession = {
    enable = true;
    windowManager.command = "systemd-cat --identifier=xmonad ${pkgs.xmoflake}/bin/xmonad";
};
home.packages = [ pkgs.xmoflake ];
#below script is only needed to be able to rebuild in place
home.file.xmonadBuildScript = {
  target = ".xmonad/build";
  executable = true;
  text = ''
    #!/usr/bin/env bash
    set -e
    # CHANGE THIS TO MATCH THE ACTUAL LOCATION OF XMOFLAKE REPO !!
    XmoflakeDir="$HOME/nixos-config/Xmoflake"

    cd "$XmoflakeDir"
    nix build

    ln -s -f -T "$XmoflakeDir/result/bin/xmonad" "$1"
  '';

Then in-place-recompilation will work for xmonad and xmobar!
To have nixos launch the xsession.windowManager.command we have defined, you can add this in nixos-config:

  services.xserver = {
    #from https://discourse.nixos.org/t/opening-i3-from-home-manager-automatically/4849/8
    windowManager.session = [{
      name = "home-manager";
      start = ''
        ${pkgs.runtimeShell} $HOME/.xsession &
        waitPID=$!
      '';
    }];
    displayManager.lightdm.enable = true;
    enable = true;
    layout = "us";
  };

If there is a less hacky way of launching home-manager's windowManager.command, please tell me :)
